The present paper aims at describing one of the important symbols of the Cieszyn and Český Cieszyn – a tram line, a cultural heritage around which the history of both border towns can be written. The history of the Cieszyn tram line in the years 1911–1921 was depicted in the first part. The second part presents its current state and various ways of commemorating the tram line (which were undertaken after 2004), such as a joint bilingual theatre project of the Polish Stage and the Czech Stage of the Tĕšínské Divadlo (Cieszyn Theatre) in Český Cieszyn. The project is entitled Těšínské niebo Cieszyńskie nebe (Cieszyn Sky). There is another cross-border project entitled “Tramwaj Cieszyński wrócił! Těšínská tramvaj se vrátila!” (The Cieszyn tram is back) and many other valuable and diverse initiatives. The third part of this article describes two big cross-border projects: 1) “An analysis of the possibility to restore the tram line as a tourist attraction in Cieszyn and Czech Cieszyn”; 2) “On the trail of Cieszyn tram line – development of the cross-border tourism”. A number of activities undertaken and implemented in the second project were specified. The subject of the longer description was the greatest tourist attraction on the reconstructed famous tram route – a faithful replica of the Cieszyn Ringhoffer. The summary underlines that both the history of the Cieszyn tram line and the process of its commemoration and restoration depended on the political and social events, which have been of international importance. It was also emphasized that the symbolism of the Cieszyn tram line has changed over the years – from a symbol of the Cieszyn and Czech Cieszyn unification and integration of the societies inhabiting them, to “a core metaphor of one city as it was before 1920”.
